The best way to plot them is by month.
170 - 110 = $60.
We are supposed to plot in months and the above calculation is in year, convert it into months
60/5 = $5 each month
So, the coordinates would be 0, 110 1, 115 2, 120 3, 125
The month will be in the x axis and your money will be the Y axis
A suitable y-axis scale to plot spending habits ranging from $110 to $170 would start at $100 and go up to $180, while a good interval for the y-axis would be $10 to allow for clear plotting of values in whole dollars.
To answer the student's question about how to plot spending habits on a coordinate grid:
A good scale for the y-axis when plotting the family's grocery bills that range from $110 to $170 would be one that fits the entire range of values without being too cramped or too spread out. For instance, a scale that starts at $100 and goes up to $180 would allow all points to be plotted clearly. Since these are monetary values, maintaining a scale that reflects currency would be logical.A good interval for the y-axis could be multiples of $10 since this allows for clear and precise plotting of bills that are likely to be in whole dollars, making the graph easier to read while still being detailed enough to discern differences of $10.a 18 ft tall statue standing next to a globe casts a 12 ft shadow. Of the globe casts a shadow that is 2 ft ling, then how tall is it?
3 ft
Step-by-step explanation:The statue's height is 1.5 times the length of its shadow, so we expect the same relationship for the globe.
... 1.5 × 2 ft = 3 ft
_____
Comment on the problem
As a practical matter, with the sun high enough in the sky to cast a shadow shorter than the object's height, it will be quite difficult to measure the length of the shadow of the point at the top of the globe. The shadow of other parts of the globe will interfere.

Write three different fractions that are less than 40%?
1/3, 1/4, 1/5
Step-by-step explanation:40% = 40/100 = 2/5
Any fraction with a numerator of 2 and a denominator larger than 5 will be less than 40%, for example.
So, we can choose 2/6 = 1/3, 2/8 = 1/4, and 2/10 = 1/5 as some such values.
_____
We could also choose something like 39.99% = 3999/10000, or 1% = 1/100.

5.5 oz = __________ kg
Answer:
0.155922
Step-by-step explanation:
Answer: 0.1562 kilograms
Step-by-step explanation: To convert 5.5 ounces into kilograms, we first convert 5.5 ounces into grams using the conversion factor 1 oz = 28.4 g.
Since we are going from a larger unit "ounces" to a smaller unit "grams" we multiply 5.5 by the conversion factor which is 28.4 to get 156.2.
This means that 5.5 ounces is equal to 156.2 grams.
Next, we convert 156.2 grams into kilograms using the conversion factor
1 kilogram = 1,000 grams. Since we are going from a smaller unit "grams" to a
larger unit "kilograms" we divide 156.2 by the conversion factor which is 1,000
and we get 0.1562 kilograms.
Therefore, 5.5 ounces is equal to approximately 0.1562 kilograms.

Lane borrowed $1200 for a new drum set. She will be paying 6.5% in simple interest over the next 2 years. What is the total amount of interest she will be paying on the loan? Show Work
Answer:
Steplo-by-step explanation:loan is 1200.
The interest rate is 6.50
Pp 46.90
Cumulative payment $53.4
Total payments$1,282.93
Final answer:
Lane will pay a total of $156 in simple interest on the loan of $1200 over 2 years, calculated using the simple interest formula: I = PRT.
Explanation:
Lane borrowed $1200 at a simple interest rate of 6.5% for a period of 2 years. To calculate the total amount of interest that will be paid on the loan, we can use the simple interest formula, which is:
I = PRT
where I is the interest, P is the principal amount borrowed, R is the interest rate per year (expressed as a decimal), and T is the time in years the money is borrowed for.
First, we convert R to a decimal by dividing it by 100:
R = 6.5% / 100 = 0.065
Next, we substitute the values into the formula:
I = $1200 × 0.065 × 2
I = $1200 × 0.13
I = $156
Therefore, the total amount of interest that Lane will be paying on the loan over the next 2 years is $156.
Segment AN is the altitude to side BC in ΔABC. If AB = 3NC and AN = 2NC, prove that AC = BN. (Hint: Use variables in such problems. Let NC = x units and find the other lengths in terms of x.)
Answer :
The proof is as follows :
Step-by-step explanation:
Let NC = x
⇒ AB = 3x and AN = 2x
In Δ ABN, By using Pythagoras theorem,
AB² = BN² + AN²
⇒ BN² = AB² - AN²
⇒ BN² = (3x)² - (2x)²
⇒ BN² = 5x²
⇒ BN = x√5 .......................(1)
Now in ΔANC , Using Pythagoras theorem We have,
AC² = NC² + AN²
⇒ AC² = x² + (2x)²
⇒ AC² = 5x²
⇒ AC = x√5 ....................(2)
From equations (1) and (2) We get,
AC = BN , which is our required result
Answer:
BN=AC=√5 x.
The proof is explained in step-by-step explaination.
Step-by-step explanation:
Let NC=x. It is given that AB=3NC & AN=2NC
⇒ AB=3x & AN=2x
By applying Pythagoras theorem
In triangle ANC,
[tex]AC^{2}=AN^{2}+NC^{2}[/tex]
⇒ [tex]AC^{2} = (2x)^{2}+x^{2}[/tex]
⇒ [tex]AC^{2}=4x^{2}+x^{2} =5x^{2}[/tex]
⇒ [tex]AC=\sqrt{5}x[/tex] → (1)
Similarly, In triangle ABN,
[tex]AB^{2}=AN^{2}+BN^{2}[/tex]
⇒ [tex](3x)^{2}=BN^{2}+x^{2}[/tex]
⇒ [tex]9x^{2} = (BN)^{2}+4x^{2}[/tex]
⇒ [tex]BN^{2}=5x^{2}[/tex]
⇒ [tex]BN=\sqrt{5}x[/tex] → (2)
From eq (1) & (2), AC=BN

The length of the rectangle is 7 inches, the width is w inches. If the coefficient of the width increases by 3, what could be an expression for the area of the rectangle?
Answer:
A = 10w
Step-by-step explanation:
In the area formula, the coefficient of width is length. Here, that is ...
... A = 7w
7 is the coefficient of the width. Increasing it by 3 makes it be 10, so we have ...
... A' = 10w
_____
Comment on the problem statement
The problem does not make it clear whether area stays the same as the coefficient increases. We have assumed that it does not.
Also, the coefficient of width in the area formula has units of inches. "Increases by 3" makes no sense in this context. It would make sense for it to increase by 3 inches. The result is very different if the increase is 3 microns, for example.
What is the area of a section of pavement that is 20 ft wide and 70 yd long?
Answer:
A = 4200 ft^2
Step-by-step explanation:
We know the formula for area is
A = l*w
We need to have the same units
convert yd to ft
1 yd = 3ft
Multiply each by 70
70 yds = 210 ft
A = 210 *20
A = 4200 ft^2
The area of the pavement section is 4200 square feet, computed by converting the length to the same unit as the width and multiplying width by length.
Explanation:The subject of this question is the calculation of the area of a rectangle. The rectangle in question is a section of pavement with a width of 20 ft and a length of 70 yd. Before calculating, it's important to have the measurements in the same units. Converting 70 yards to feet (since 1 yard equals 3 feet) we get 210 feet. The formula to calculate the area of a rectangle is Area = Width x Length. Substituting the given values into the formula, we get: Area = 20 ft x 210 ft which equals 4200 square feet. Therefore, the pavement section's area is 4200 square feet.

What is the Value of x+y ? PLZ Help ASAP
Answer:
x + y = 60
Step-by-step explanation:
In the given figure, we have two lines that intersect each other at one point.
Therefore, the opposite angles are equal to each other and we can write them in the form of an equation as:
2y - 5 = 95 --- (1)
3x + 55 = 85 --- (2)
Now solving each of the equations to find the value of x and y.
For y:
2y - 5 = 95
2y = 95 + 5
2y = 100
y = 50
For x:
3x + 55 = 85
3x = 85 -55
3x = 30
x = 10
Therefore, x + y = 10 + 50 = 60.

Answer:
The cost of the wristband for 8 rides is $35.
Step-by-step explanation:
The expression for the cost, C, for r rides is
C = 2.5r + 15
Since she wants to go on 8 rides, r is 8.
Substitute r with 8 in the cost equation and evaluate it.
C = 2.5r + 15
C = 2.5 * 8 + 15
C = 20 + 15
C = 35
The cost of the wristband for 8 rides is $35.

Jose and Jenna competed in a bike race. After 30 minutes, Jose had finished 2/3 of the race and Jenna had finished 7/12 of the race. Who had finished more of the race?
Final answer:
After converting their completion fractions to decimal form, Jose finished more of the race than Jenna after 30 minutes, with Jose at 2/3 (approximately 0.6667) and Jenna at 7/12 (approximately 0.5833).
Explanation:
Jose and Jenna competed in a bike race. After 30 minutes, Jose had finished 2/3 of the race, and Jenna had finished 7/12 of the race. To determine who had finished more of the race, we can compare these two fractions by finding a common denominator or converting them to decimal form.
First, let's convert them to decimal form:
2/3 is approximately 0.6667
7/12 is approximately 0.5833
Comparing the decimal values, we can see that Jose's completion (0.6667) is greater than Jenna's (0.5833). Therefore, Jose had finished more of the race after 30 minutes.
i need help on finding the orthocenter of a triangle, i got the x right, x=6 but I got the Y value wrong, it's supposed to be y=4 but i got y=8 as my answer. the question is find the coordinates of the orthocenter of Triangle ABC with vertices A(2,6), B(8,6), and C(6,2). what i did to find the Y value was find the slope of BC then use that value and the coordinates of A and substituted them into an equation y-6=1/2(x-2), i solved it and got y = 1/2x+5. i then substituted my x value that i previously found into it to find Y , y=1/2(6)+5 . i got 8 as the Y value but it's wrong, can someone tell me what i missed?
Answer:
See the attached
Step-by-step explanation:
When in doubt, draw a diagram.
The orthocenter of this acute triangle will be within its bounds. That should tell you right away that the y-coordinate of it will not be 8, but must be between 2 and 6.
The line perpendicular to BC through A must have a y-intercept greater than the y-coordinate of A, so cannot be 5. Whatever it is, the y-coordinate of the orthocenter will be less, so again, your answer fails the reasonableness test.
The perpendicular line to BC through A is ...
... y = (-1/2)(x -2) +6 = -x/2 +7 . . . . . . looks like you had a sign error in (-1/2)(-2)
The intersection of that line and x=6 is ...
... y = -6/2 +7 = 4

A college survey was taken to determine where students study. Of 147 students surveyed, 92 studied in the cafeteria, 86 studied in the student lounge, 40 studied in both the cafeteria and the student lounge. Of those interviewed how many did not study in either the cafeteria or the student lounge?
9 students did not study in either the cafeteria or the student lounge.
How to find the number
To find the number of students who did not study in either the cafeteria or the student lounge, we solve as follows
Let
C = 92
L = 86
C ∩ L = 40
We find the number in either C, L or C ∩ L
= (92 - 40) + (86 - 40) + 40
= 52 + 46 + 40
= 138
The number did not study in either the cafeteria or the student lounge
= 147 - 138
= 9

Find a recursive formula for the sequence:
3, -5, 11, -21
The correct option is the last:
[tex] a_n = -2a_{n-1}+1 [/tex]
In fact, every term in the sequence is one more than twice the opposite of the previous one:
We start with 3. Twice its opposite is -6. Plus one, we get -5.
We start with -5. Twice its opposite is 10. Plus one, we get 11.
We start with 11. Twice its opposite is -22. Plus one, we get -21.
The recursive formula is: [tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]
To find a recursive formula for the given sequence, we need to determine the relation between consecutive terms.
Let's denote the sequence as an, where:
[tex]a_1 = 3\\a_2 = -5\\a_3 = 11\\a_4 = -21\\[/tex]
First, let's calculate the differences between consecutive terms:
[tex]a_2 - a_1 = -5 - 3 = -8\\a_3 - a_2 = 11 - (-5) = 16\\a_4 - a_3 = -21 - 11 = -32[/tex]
We observe that each difference is a multiple of 8 and that each difference is twice the previous difference but with alternating signs.
The recursive formula can be defined as:
[tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]
Thus the recursive formula is: [tex]a_n-a_{n-1} = (-8)(-1)^n \times (2)^{n-2}[/tex]

Answer:
2^(8/9) in²
Step-by-step explanation:
Make use of the identity ...
... (a^b)^c = a^(bc)
Here, you have a=2, b=4/9, c=2. There is an additional factor (units of inches) inside the parentheses on the left. For that, you use the identity
... (ab)^c = a^c·b^c
In this case a = 2^(4/9), b = in, c = 2.
So, the working of your problem is ...
... Area = (side length)^2 = (2^(4/9) in)^2 = (2^(4/9))^2 in^2
... = 2^(4/9·2) in^2 = 2^(8/9) in^2
To the nearest whole degree, what angle measure has a tangent of 2.0874?
The angle of elevation from a soccer ball on the ground to the top of the goal is 34. If the goal is 8 feet tall, What is the distance from he ball to the goal?
Answer:
The distance from he ball to the goal is 11.85 feet (Approx) .
Step-by-step explanation:
As given
The angle of elevation from a soccer ball on the ground to the top of the goal is 34° .
If the goal is 8 feet tall.
Now by using the trigonometric identity .
[tex]tan \theta = \frac{Perpendicular}{Base}[/tex]
As shown in the diagram given below
[tex]\theta = 34^{\circ}[/tex]
Perpendicular = AB = 8 feet
Base = BC
Put all the values in the identity .
[tex]tan\ 34^{\circ} = \frac{AB}{BC}[/tex]
[tex]tan\ 34^{\circ} = \frac{8}{BC}[/tex]
[tex]tan\ 34^{\circ} = 0.675\ (Approx)[/tex]
[tex]BC = \frac{8}{0.675}[/tex]
BC = 11.85 feet (Approx)
Therefore the distance from he ball to the goal is 11.85 feet (Approx) .
To calculate the distance from the soccer ball to the goal with an angle of elevation of 34 degrees and a goal height of 8 feet, use the tangent trigonometric ratio. The distance is found to be approximately 11.86 feet.
Given the angle of elevation is 34 degrees and the goal's height is 8 feet, we're looking to calculate the adjacent side (distance from the ball to the goal) in a right-angled triangle where the opposite side (goal's height) and the angle are known.
To calculate the distance (let's call it d), we use the tangent function:
tan(angle of elevation) = opposite/adjacenttan(34 degrees) = 8/dSo, d = 8/tan(34 degrees).
Calculating this, we find:
d ≈ 8/0.6745d ≈ 11.86 feetTherefore, the distance from the soccer ball to the goal is approximately 11.86 feet.
